The only reason anyone buys a forum account is to trick people, either when trading, or to bypass rules for bounties and signature campaigns.

Once you realized you bought a stolen account you had a choice, return it to the rightful owner, or keep it.

What right do you have to keep a stolen account, the person who 'owes' you is the person you bought it from, not the original victim of the account theft.

If you keep a stolen account and pretend it's yours, you're a scammer!
